Unable to run multiple MSI Radeon RX 550 AERO ITX 4G

[juggernautsei]

I purchased my rig gear 2 months ago on 9/14/2017.

1 x ASRock H110 Pro BTC+ LGA 1151 Intel H110 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

12 x MSI Radeon RX 550 DirectX 12 RX 550 AERO ITX 4G OC 4GB 128-Bit GDDR5 PCI Express x16 (Uses x8) HDCP Ready Video ...

Using windows 10 home edition.

Video driver installed in version 17.7.1 right now.

It crashes with just one card in the system.

I chronicled a lot of what has been going on with this rig here https://github.com/nanopool/Claymore-Dual-Miner/issues/114#issuecomment-334753341.

I tried talking with MSI but their only concern is "does the card show video". It does. So that is as far as they go because of course, they can warranty the card for any kind of performance in mining an unsupported use of the card.

I have tried to underclock the cards and I have tried to overclock. Everything fails.

These are not working in any kind of capacity for long periods of time meaning more than a couple of hours at best before the whole thing locks up.

What I see most is the screen will start to flicker. That is the prelude to it going down. The blue screen that displays one of three things.

Thread Stuck, Video Scheduling, of Not responding.

My first rig was with Sapphire AMD RX 550. That rig is a dream compared to this one.

I have not had one moment's trouble out of it in 3 months. It is running the H81 ASRock board.

I am at my wits end on this one. It is getting close to that time to just break it up and sell off the pieces.

Any suggestion

Where is the subtopic?

Put last driver (17.11.2), download latest windows update (1709) before
anything else

So what kind on performance do you get from the 550? Also what do you mine?

So what kind of performance do you get from the 550? Also, what do you mine?

The performance is 8 - 9 MH/s on each card. With 6 cards, the rig one is clocking about 54 MH/s. That is with no overclocking or under volting.

Right now I am in the middle of switching from windows to Linux based mining software.
Windows on my second rig keep crashing.
